A public service announcement for Mad magazine readers, and those who love them: More than 400 of Al Jaffee's fold-ins from the inside back covers of almost every issue are collected in four volumes covering 1964 to 2010 ($125, Chronicle Books, www.chroniclebooks.com). Give the set and maybe, just maybe, you can clear those back issues from the garage or attic.

Hey ho, hip coolio! Get down with your sweet self, materialist that you aren't, and give the gift of groove. The Soulo microphone ($69, www.apple.com) transforms an iPad 2 into a lean and mean karaoke machine, one that's capable of filming performances, cringe-worthy as they may be.

Convert beloved vinyl tracks into digital duplicates with Crosley's portable USB turntable ($149.95, www.crosleyradio.com) and listen to them on UrbanEars plattan headphones ($68, for Bay Area retailers see www.urbanears.com).
